I know, it's awful to debug various combinations of various levels of
headings... We don't have this completely right in out math journal
(typeset by TeX) either, I'm afraid.

Looking at the code, I suspect this might be the reason:
% If there are two @def commands in a row, we'll have a \nobreak,
% which is there to keep the function description together with its
% header. But if there's nothing but headers, we want to allow a
% break after all.
\ifnum\lastpenalty=10000 \penalty0 \fi
Perhaps we need other method to trace two @def's in a row.
What about implementing it via an \if?
Or is it possible to use \penalty10001 to mark the special case?
I have no time to try to write a patch, not speaking about testing,
at least at the moment.
Sorry, Karl.
Stepan
